This interview was conducted by Atiya Henry, Commissioning Editor of . Joseph M Blondeau, MSc, PhD, RSM(CCM), SM(AAM), SM(ASCP), FCCP is a Clinical Microbiologist and Head of Clinical Microbiology at Royal University Hospital (Saskatoon Health Region) and the University of Saskatchewan in Saskatoon, Canada. He is also the Provincial Clinical Lead for Microbiology in Saskatchewan, Canada. He holds a Masters of Sciences in Microbiology from Dalhousie University (1985) and a Doctor of Philosophy in Medical Microbiology from the University of Manitoba (1989). Following completion of his PhD, he completed an 1-month post-doctoral training in an infectious diseases research laboratory at Dalhousie University and following which he completed a 2-year post-doctoral residency training program in Clinical Microbiology, also at Dalhousie University. He holds appointments as a Clinical Associate Professor of Pathology, Adjunct Professor of Microbiology and Immunology and Clinical Associate Professor of Ophthalmology. He teaches to undergraduate and graduate students in the areas of microbiology, infectious diseases, antimicrobial agents and pharmacology. Dr Blondeau's main research interests are in the area of antimicrobial agents and antimicrobial resistance, clinical microbiology and clinical outcomes associated with antimicrobial therapy in both human and veterinary medicine.

This article precedes a series of articles on the important questions, hypotheses and theories in microbial ecology. It considers why, as scientists, we ask questions and propose hypotheses and what makes them important, good or significant. Emphasis is placed on 'scientific' questions, the need for scientific aims and on possible reasons for, and inadequacy of aim-less studies and question free studies. Current global issues surrounding the climate crisis, pandemics and antibiotic resistance focus attention on science and scientists. They exemplify the urgent need for greater understanding of the interactions between microbes and their biological and physicochemical environments, that is, of microbial ecology. They also provide examples of reaction against science and scientists and highlight why we must be clear regarding what defines (good) science, its power and limitations, and ensure that this is communicated to stakeholders and the general public.

Review
The rhizosphere is a chemically complex environment that harbors a strikingly diverse microbial community. The past few decades have seen a rapid growth in the body of literature on plant-microbe-microbe interactions and plant health. Thus, the aim of this paper is to review current knowledge on plant-microbe-microbe (specifically bacteria) interactions in the rhizosphere and how these influence rhizosphere microbiomes and impact plant health. This article discusses (i) how the plant recruits beneficial rhizosphere bacteria and ii) how competition between rhizosphere bacteria and mechanisms/weapons employed in bacteria-bacteria competition shapes rhizosphere microbiome and in turn affects plant heath. The discussion mainly focuses on interference competition, characterized by production of specialized metabolites (antibacterial compounds) and exploitative competition where a bacterial strain restricts the competitor's access to nutrients such as through secretion of siderophores that could allude to cooperation. Understanding mechanisms employed in bacteria-bacteria and plant-bacteria interactions could provide insights into how to manipulate microbiomes for improved agricultural outcomes.

Review
Streptomyces, the most abundant and arguably the most important genus of actinomycetes, is an important source of biologically active compounds such as antibiotics, and extracellular hydrolytic enzymes. Since Streptomyces can have a beneficial symbiotic relationship with plants they can contribute to nutrition, health and fitness of the latter. This review article summarizes recent research contributions on the ability of Streptomyces to promote plant growth and improve plant tolerance to biotic and abiotic stress responses, as well as on the consequences, on plant health, of the enrichment of rhizospheric soils in Streptomyces species. This review summarizes the most recent reports of the contribution of Streptomyces to plant growth, health and fitness and suggests future research directions to promote the use of these bacteria for the development of a cleaner agriculture.

The reconstruction of bacterial and archaeal genomes from shotgun metagenomes has enabled insights into the ecology and evolution of environmental and host-associated microbiomes. Here we applied this approach to >10,000 metagenomes collected from diverse habitats covering all of Earth's continents and oceans, including metagenomes from human and animal hosts, engineered environments, and natural and agricultural soils, to capture extant microbial, metabolic and functional potential. This comprehensive catalog includes 52,515 metagenome-assembled genomes representing 12,556 novel candidate species-level operational taxonomic units spanning 135 phyla. The catalog expands the known phylogenetic diversity of bacteria and archaea by 44% and is broadly available for streamlined comparative analyses, interactive exploration, metabolic modeling and bulk download. We demonstrate the utility of this collection for understanding secondary-metabolite biosynthetic potential and for resolving thousands of new host linkages to uncultivated viruses. This resource underscores the value of genome-centric approaches for revealing genomic properties of uncultivated microorganisms that affect ecosystem processes.
